Does point-of-care ultrasound (POCUS) improve the early diagnosis of postprocedural arterial pseudoaneurysms in the emergency department?
POCUS is an effective first-line imaging modality for the early detection and diagnosis of postprocedural arterial pseudoaneurysms in the emergency department, streamlining consultation and optimizing patient care.
Supports POCUS for rapid ED pseudoaneurysm detection; leaves open need for prospective validation before practice change.
This narrative aims to evaluate the efficacy of point-of-care ultrasound (POCUS) in the early diagnosis and management of postprocedural arterial pseudoaneurysms in the emergency department (ED). We hypothesize that POCUS can be used as the first line of imaging to distinguish vascular from non-vascular causes and diagnose a pseudoaneurysm if present. A comprehensive review of cases involving postprocedural pseudoaneurysms was conducted. We focus on patients who underwent endovascular procedures, including transfemoral and transradial arterial access for cardiac interventions, or received laceration repair after blunt head trauma. We analyzed each case's clinical symptoms, POCUS findings, and subsequent management. POCUS demonstrated high efficacy in early diagnosis by detecting pseudoaneurysm sacs with characteristic bi-directional flows (yin-yang sign) and, in some cases, partial thrombosis. The early identification of potential arterial complications allowed for efficient planning of further imaging and expedited surgical consultation, leading to timely and definitive management. Our study emphasizes the significance of using POCUS as the primary imaging modality for early detection and diagnosis of postprocedural arterial pseudoaneurysms. Incorporating POCUS into the initial assessment of patients presenting with pain and swelling at the site of arterial access or laceration repair can streamline consultation and potentially reduce the need for additional imaging, optimizing patient care in the ED setting.

Azzo et al. (2023) conducted a case report in Postprocedural arterial pseudoaneurysms (n=4). Point-of-care ultrasound (POCUS) was evaluated on Detection and diagnosis of pseudoaneurysm. Point-of-care ultrasound successfully identified postprocedural arterial pseudoaneurysms by detecting sacs with characteristic bi-directional flows, facilitating rapid diagnosis and surgical consultation.
